Be it known that I, AUGUST BAUsoHm- CHER, a subject of the Emperor of Germany, residing at Stegstrasse ('4, SachenhausenF Frankfort-on-thefl/Iain, Germany, have 11'1- vented .certain new and,v useful Improvements in Gages, of which the following is a specication, reference being had therein to the accompanying drawing.

My invention relates to gages and more especially to that class of-gages whereinl there is employed one or more `gage-pieces such as spheres for determining the dimen sions of the objects to be measured or gaged.

The present invention contemplates in connection with each of the gage-pieces or spheres a holding device, the gage-piece and the holding device having certain characteristics, as will hereinafter appear.

I will first describe one or morev forms in which my improvements may be embodied and will then point out the novel features in the claims.

Figure 1 is a central longitudinal section of 'a gage embodying my improvements. Fig. 2 is an outside view of the same. Fig. 3 shows a modification differing from the first form. in several details; and Fig. 4 illustrates'a further modification.

Similar letters of reference arel employed to designate corresponding parts in the several figures of the drawings.

In the first form, namely that illustrated in Figs. l and 2, there is only av single gagepieceshown, and this gage-piece is seen to be spherical or partly spherical, it consisting preferably of' a hardened steel ball recessed in the manner to be herein described.

A represents such a spherical gage-piece. lVhen only one of them is employed in a gage the gage will be used, for example, for determining' the accuracy of interior diameters or bores, and to this end the steel sphere will be scientifically constructed or selected as of the proper diameter. It will be understood that although I illustrate only la single gage, an entire series may be e111-,

ployed of graduated sizes, and in any case it will be a convenience to have stamped or etched upon each of the .gagepieces, the proper characters to indicate the diameters thereof, for example the figures 1%; are shown on the exterior of the gage-piece in Fig. 2.

- According to my invention the gage-piece Specification of Letters Ilatent. j Patented SEIN?. 2, 93. i Application med November 12, i910. serial N9. 591,952."

A is tobe provided-with a'projecting portion capable ofvlocking with the holder or handle to be describedgthe latter being a device having jaws adaptedto engage 'around and lock with the projecting portion of the gage-piece.

A projecting portion a such as my invention contemplates may be produced upon a' preformed steelv sphere by a process of milling an annular recess at d at one side of the sphere, as clearly seen' in lFigs. l and 2.'v v` The body of the handle B is shown as of a tubular lform and substantially rigid from its. extremity up to the point where the yielding jaws b `are formed.

The jaws o may be described as of a form :mitted by the presence lof one or more sl'ots as shown at b.

which first diverges and then converges so as to produce near the middle portion'of each jaw an outward extension. The extreme ends of the jaws being converging, readily engage with and grasp the diverging projection a ofthe gage-piece.

IVhen the handle and gage-piece are engaged in this manner, the jaws are intended to be locked in place so as to permanently hold together the handle and gage-piece against accidental separation. A convenient locking means is the ring C capable of sliding longitudinally over'the handle B and of such construction and diameter that when forced toward or against the jaws b it will act with a wedging operation to squeeze or compress the jaws together and in this Way permanently securing them in the position shown. f j

`The above described construction may obviously be varied in many minor details and other mechanical expedient-s may be substituted for the particular details illustrated. For example, in Fig. 3 the handle B is constructed not of a hollow or tubular form, but of a solid piece of metal which has been bored into at the jaw end for the formation tut es a nnt which may he tightened or looked to a greater degree of eccnrity, rigidity and jxernianezlee than in the other instances. What l1 claim as new and desire to secure hy Lettere Patent', is:

l. plugin* here gagccomprising in coinl ination a one-piece gagging element adapted to enter the here o1' interior to be gaged and al'ford all the nagging contacts therefor., and a separate liandlc, .said gage-piece pro vided 'with a projecting portion capable of locking with the handle, and said handle having jaws adapted to lock with Said projection. y

52. 1. nlug or here gage comprising in comhination a onefpiece gaging element adapted to enter the here or interior tovhe gaged'and at'fcid all the Ygagging); contacts therefor, and

a separate handle, and gage-piece provided 1 with a. projecting portion ca able vof locking with the handle, and said andle having tapered jaws adapted to lock with said projection, and a locking" ring movable over said jaws.

3. A plug or 'ocre gage comprising in combination a one-piece gaging element adapted to enter the bore or interior to be gaved and afford all the gagging contacts therefor, and a separate handle, said gage-piece provided with a projecting portion capable of lockimgr with the handle, and said handle having tapered and threaded jaws adapted to loc with Said projection, and a threaded locking ring engaging the tlneadr on said jaws.

4. A gage comprising in combination a hardened steel sphere cut away to aford a diverging lng, adapted to lock with such projection.

5. A gage comprising in combination a hardened steel sphere cut away to alford a diverging lug, and a handle having jaws adapted to lock with such projection, and a locking,r device for said jaws. l

ln testimony whereof I affix my signature in presence of two witnesses.
